subspecies liere, and is easily separable from the typical form 

 by its more brilliant coloration.

The Rufous Warbler is not uncommou in the Wadi 

 Natron during the summer. I was too early for this species 

 during my visit, but Mr. Balboni has sent me specimens 

 and eggs. 



ACROCEPHALUS STBEPERUS STREPERUS (Vieill.).

I first met with the Reed-Warbler on March 19th, 1910, 

 in some bulrushes near one of the Salt Lakes, when I 

 obtained two males, while during the next few days I saw 

 many others. 



Compared with British examples, specimens from Egypt 

 seem to be much less rufous in coloration, though they are 

 not nearly grey enough for A. s. macronyx. At present I 

 must imite them with the typical form, but I think that 

 subsequent researches may shew that there is at least 

 another geographical race of this species.

The Egyptian and Palestine form of the Clamorous Great 

 Reed- Warbler appears to be resident in the Wadi Natron. 

 I saw several during my visit in March. 



Loat obtained it in February, and Mr. Balboni has sent me 

 a nearly full-grown young bird obtained on June 8th, 1910. 



In November 1911 I found many examples of this 

 species.

First met with on March 19th, after Avhich date it became 

 fairly abundant in the bulrushes round the Salt Lakes up 

 to the time of my departure.
